The ascent of a hot spherical body through a fluid with a strongly temperature-dependent viscosity has been studied using an axisymmetric finite element method. Numerical solutions range over Peclet numbers of lo-'-lo3 from constant viscosity up to viscosity variations of 10'. Both rigid and stress-free boundary conditions were applied at the surface of the(More)
